Kunkle Valve 0930-J01-GC0015 Pressure Relief Valve

The Kunkle Valve 0930-J01-GC0015 is a high-capacity ASME Section IV steam pressure relief valve designed for industrial and commercial low-pressure steam heating boilers. This cast iron safety relief valve features a 2 1/2" Male NPT inlet and a 2 1/2" Female NPT side outlet, providing a robust relief solution with a 4501 lb/h steam capacity. Engineered for 15 PSI set pressure applications, the 0930-J01-GC0015 serves as a direct replacement for 0216019, ensuring seamless integration into existing boiler systems. The internal trim consists of a bronze nozzle, disc, and guide, which are lapped to provide a superior seal and consistent performance. A National Board certified component, it includes a reversible lift lever for manual testing in "pull-up" or "pull-down" configurations. Every unit is factory sealed to maintain calibration and prevent unauthorized tampering, ensuring critical system protection at operating temperatures up to 250°F.

• ASME Section IV Certified: Specifically engineered for low-pressure steam heating boilers, ensuring compliance with the ASME HV standard.
• High Flow Capacity: Delivers a 4501 lb/h capacity at a 15 PSI set point, making it suitable for large-scale boiler applications.
• Superior Seat Performance: Features a large seat-to-guide area ratio and a disc pivot design for reliable valve reseating and minimal leakage.
• Direct Compatibility: Functionally identical to the Kunkle 0216019, allowing for immediate field replacement.
• Corrosion Resistant Internals: The bronze disc and guide offer excellent resistance to steam-related scaling and corrosion.

Common Questions

What systems is this pressure relief valve compatible with?
This valve is designed exclusively for low-pressure steam boilers. It is ideal for commercial, industrial, and large residential heating systems requiring an ASME Section IV rated safety device set at 15 PSI.

Can the set pressure be field-adjusted?
No, the set pressure is factory-fixed at 15 PSI and the valve is sealed to prevent tampering. Any adjustment in the field will void the National Board certification and may compromise system safety.

What is the proper orientation for installation?
To facilitate self-draining and ensure the spring-loaded mechanism functions correctly, this valve must be mounted in a vertical position with the inlet facing downward.
